The fine salad oil is made from this fruit, for which purpose they are gathered ripe; for pickling they are gathered when only half ripe, at the latter end of June; they are put into fresh water to soak for a couple of days; after this they are thrown into lime-water, in which some pearl-ashes have been dissolved; in this liquor they lie for six and thirty hours; they are then put into water which has had bay-salt dissolved in it; this is the last preparation, and they are sent over to us in this liquor; they are naturally, as they grow on the tree, extremely bitter, and therefore all these preparations are necessary to bring them to their fine flavor. To some olives they add a small quantity of essence of spices, which is an oil drawn from cloves, nutmeg, cinnamon, coriander, and sweet fennel-seed distilled together for that purpose; twelve drops are sufficient for a bushel of olives; some prefer them flavored with this essence.
